IMPRQVEMENT 1N Pomme-CHAIRS.

The S'dhedulle referred t -in these Letters Patent and making part ofthe same.

To all whom it lmay concern Be it known that we, WILLIAMMORSTA'IT andFRANCIS Krrs, both ot' the city of New York, in the county and State ofNew York, have jointly iuvented a newand improved FoldingGhair;`and wedo` hereby declare that the followingis a full, clear, and exactdescription thereof, reference being hadto theaccompauying drawingforming part of this speeification.

Figure I represents a'side view of our improved chair, showing the samefolded together.

, Figure II is a side' elevation `of the same, showing the chairextended, to form a sofa'or lounge.

Figure III is a iront view of the extending part of the chair. l

Similar letters indicate' corresponding parts in all the figures. l

This invention consistsfin the construction of-a strong frame or stool,forming (when extended) the rear part vof the lounge or sofa, and 4uponwhiclrtlie seat of the cha-ir is supported, and connected withthe sameby means 'of arms or levers.

Further, in the arrangement of the back, hinged to the frame or stool,.and provided with arms, through which the chair, when folded, is firmlyfastened or lockedtogether and combined with levers fast in the frame orstool, and operated by asuitable screw, through which, when the chair'isextended, the position or inclination of the back can be changed anregulated; and

' Further, in the arrangement and construction of a suitable oot-board.

In the accompanying drawing` A represents a-st-rong frame or stool,provided with suitable legs, B B. e

E is a stool, provided withtwo short legs, a, and two long legs, F,corresponding in height \vith'.t-he legs B on the stool A. I

The legs F have projections a, corresponding in height with the shortlegsa, and said legs 'a and projeetions a rest upon the frame of thestool A, and support the stool E, which latter forms the seat of thechair, .when folded, (see Fig. I,) and the front part of the lounge orsofa, when extended, (see Fig. II.) I

This stool E is connected with the stationary stool A ,through arms orlevers, G,.turning ou a center, e', fast in the frame of the stool A,and resting upon a suitable projection, S, on said stool A, when thechair is extended, (see Fig. II,) supporting thereby the after part ofthe stool E, without any complicated slides or bolts.

I) is the hack of the chair, hinged, lat o, to the lowerl stationarystool A, and provided with arms H,

turning on centers x, fast in the back D.

The forward ends of the arms H are provided, at their under side, withprojections m, fitting, when the chair is folded, into a mortise in thestool E, (see Fig.

I,) and lock thereby the same, as well as all parts of the chair,firmlyv together.

IVhen the chair '4 extended, to form a lounge or sofa, as represented inFig. II, the project-ions at of the arms H enter into a suitable recessin the frame A, and bear against levers'J.-

'lhese levers J are fastened to a shaft,d,'capahle of vturning insuitable bearings in the-frame of thestool A, and which`said shaft disprovided with a le- Ver, N, operated by a screw, P.

By the operation of this screw I the levers J are moved either forwardor backward, acting thereby` against the projections m, fast to the armsH, so as to increase or diminish the inclination of the-back D, to whichthe arms H are hinged, and, at thc same time, retain said back D in anydesired'position.

' Io the front -of the stool'E twolevers, 2, are hinged, -between whicha foot-board, L, (see Fig. III,) is fastened, capable o f a slightmot-ion upward 'or downward.

To' thisfoot-board L projections -are attached.

When the chair is folded, this foot-'board L is allowed to hangdownward, as shown in Figs. I andv III, and when the chair is extended,and converted into a lounge or sofa, thefootboard L is turned upward andmoved slightly downward upon the levers 2, until its projections 5 passinto suitable holes, 8,

provided on the, front of the stool E,'whereby the same is lheld firm inits required upward position, as represented in Fig; II.

Having thus described our invention, l l We claim as new, and desire tosecure by Letters Patent- 1. The movable stool E, constructed with thelegs F and the-short legs or projections a n, and arranged,

in combination with thestationary chair orl stool A, by means of thepivoted connecting-arms G, Iso as to be self-supported in an uprightrposition, either upon the, stationary stool or in front of it, substan-Y tially as and for the purpose hereiuspeciiied.

2. The'arms H, pivoted to the back I), andpro vided with the projectionsfm., arranged so as to hook into the stool E, to 'hold the hack in anupright position, and inte'the stool A, to hold the back in a re-vclining position, substantially as herein specified.

8. The levers J, with their adjusting-arms N,- operated by the screw P,in combination with `thevpivotcd arms H, for the purpose specified.

4. The arrrangement of' the foot-board L, provided with projections 5and arms 2, hinged to the front of the stool E, in combination withsuitable holes 8,-.in the manner and for the purposeset forth and Ilelscribed.v
